Snipey, Op fire (shooting at your opponent during his phase) is controlled by range in the DL version. In the CD version, you have control over range AND unit type, front armor rating and perhaps hex. I haven't figured out that last yet. Maybe if I could RTFM ( Read The fine Manual) but it looks like to can select a hex and bore sight that hex. One day I'll play with it and see what happens.
Anyway, you mail your half of the turn (phase) by attaching it to an e-mail. A fast paced game would be 2 or 3 turns per day. So you are looking at a couple of weeks if everything goes well.
There is a hotseat option. That requires you find another player that lives close enough to go and visit one another. In those game time limits are normal, although they are just between players and not automated or part of the game. I used to play a lot of hotseat and you can run a game by in a few hours. SP is IGO_UGO, which doesn't really lend itself to interactive online gaming.
